 ## About
 
-The book was written and tested with Python 3.5, though other Python versions (including Python 2.7) should work in nearly all cases.
+The book was written and tested with Python 3.5, though the code has been updated to work with modern Python versions (3.8+). Most examples will work correctly with Python 3.8 and later versions.
 
 The book introduces the core libraries essential for working with data in Python: particularly [IPython](http://ipython.org), [NumPy](http://numpy.org), [Pandas](http://pandas.pydata.org), [Matplotlib](http://matplotlib.org), [Scikit-Learn](http://scikit-learn.org), and related packages.
 Familiarity with Python as a language is assumed; if you need a quick introduction to the language itself, see the free companion project,
